Multi-Topology OSPFv3 for IPv4-mapped IPv6
This memo defines two new Multi Topology Routing Identifiers (MT IDs) in OSPFv3 [RFC2740]). These new MT-OSPFv3 [I-D.ietf-ospf-mt-ospfv3] topologies are meant to convey routing information which is restricted to IPv4-mapped IPv6 addresses [I-D.ietf-behave-address-format]. The goal of running separate instances for IPv4-mapped IPv6 routes is to isolate the IPv6 routing table from the IPv4 routing table, and to avoid any overload due to the population of the table by IPv4-inferred routes. This isolation is motivated also from an operational perspective to enforce specific routing policies for each topology.
